Answer:
6 light years = 57 million km
Explanation:
Given;
A light year = 9.5 million km
To calculate how far is 6 light years;
6 light years = 6 × 1 light year = 6 × 9.5 million km
6 light years = 57 million km
Answer:
57 million kilometres
Explanation:
We are given that:
1 light year = 9.5 million kilometres
To get 6 light years, we simply multiply 6 by 9.5 million kilometres:
6 light years = 6 * 9.5 million= 57 million kilometres
St Bernard's star is 57 million kilometres away from the earth.

The correct answer is compound
Answer:
v= s/t
Explanation:
250 km/ h =69.44m/s
S1=2 times 69.44 ≈ 139m
Next 2.5 seconds:
S2 = 100m
Average speed:
v=139m+100m/2s+2.5s = 239/4.5s = 53.2 m/s=192km/h
